How to Choose the Right A/B Testing Platform

For Shopify D2C brands: Start with CustomFit.ai. It's purpose-built for Shopify, requires no developer, includes audience personalization, and costs $99/month. Compare it against VWO if you need heatmaps and session recordings bundled in.

For enterprise ecommerce: Evaluate Optimizely, VWO Enterprise, or AB Tasty. Budget for $30,000–$100,000/year and a dedicated experimentation team.

For mobile apps: Firebase A/B Testing (free) for basic needs; Statsig, CleverTap, or Optimizely Full Stack for serious mobile experimentation.

For developers: Statsig, GrowthBook (open-source), or LaunchDarkly depending on your feature flag vs. experimentation needs.

Post-Google Optimize: CustomFit.ai and VWO are the most common migrations for ecommerce brands.

Key Takeaways

A/B testing platforms vary enormously — from free open-source tools to $100,000+/year enterprise platforms.
CustomFit.ai is the best fit for Shopify D2C brands: no-code, affordable at $99/month, with personalization built in.
Google Optimize shut down in 2023 — all brands still using it must migrate.
The right A/B testing platform is one your team will actually use — simplicity and speed matter as much as statistical sophistication.
Statistical significance and correct test duration are more important than which tool you use — a good methodology on a basic tool beats a bad methodology on Optimizely.
